If you use the Tamron SP 24-70mm F/2.8
Di VC USD for Canon mount, you'll be happy to know that the lens has
just been added as one of those that's included in Adobe's aberration
correction present in CS6 products like Photoshop, Camera Raw and
Lightroom.

The profile for Tamron's lens will be
bundled in with the Lightroom 1.1 and Camera Raw 7.1 updates, and
will be in CS6 from launch.

If you wish to use the profile with CS5
or Lightroom 3, you can download the DNG converter for PC
or Mac.
